        Desolation comes from the sky: Invasive Hymenoptera species as prey of Chilean giant robber flies (Diptera: Asilidae) through field observations and citizen science

        Rodrigo M. Barahona-Segovia,Laura Pañinao-Monsálvez 한국응용곤충학회 2020 Journal of Asia-Pacific Entomology Vol.23 No.3

        Robber flies (Asilidae) are the main predatory fly family feeding on beetles, butterflies, other flies for true flies, and even spiders; however, Hymenoptera is the most common prey. Invasive Hymenoptera species are common in central and southern Chile; however, few predators of these are known. The hunting behavior and prey of Chilean robber fly species are also poorly known. The aim of this study is to provide the first hunting behavior records of five Chilean giant robber fly species on invasive Hymenoptera. In addition, an updated distribution of these species is provided. Records of hunting behavior were based on fieldwork collections and citizen science observations. The historical distribution was compared with citizen science observations using chi-square analyzes. Twelve predation events were recorded. Obelophorus terebratus was the most common predator. Bombus terrestris was the invasive Hymenoptera most preyed upon. Both the extension of occurrence of Lycomya germainii as Obelophorus species showed changes in his distribution. Only O. landbecki shown changes in area of occupancy. Citizen science is playing a key role in the knowledge of biological interactions and distribution of endemic and native Chilean robber fly species.

        Stevenia deceptoria (Diptera, Rhinophoridae): Chile’s second woodlice-parasitizing fly species studied using citizen science

        Barahona-Segovia Rodrigo M.,Mulieri Pablo R.,Pañinao-Monsálvez Laura 한국응용곤충학회 2024 Journal of Asia-Pacific Entomology Vol.27 No.1

        Stevenia deceptoria is a woodlouse-parasitizing fly species that has recently been introduced into South America and was until now known only in Argentina. In those countries it has invaded, this exotic fly prospers in cities because of the abundance of potential hosts in gardens and public parks. Here we show that S. deceptoria has been detected in urban ecosystems in the Metropolitan and Valparaíso Regions using citizen science and we describe its current range in the city and the degree of overlap between its range and that of its potential hosts. Records of both woodlouse-parasitizing flies and their hosts were obtained from two citizen science platforms: Facebook and iNaturalist. The extent of occurrence (EOO) and area of occupancy (AOO) were calculated for S. deceptoria and different woodlouse species. We assessed the advance of S. deceptoria into the city, comparing classic EOO and α-hull mode with a chi-squared test with Yates’ continuity correction. We found that S. deceptoria was widely distributed in the Metropolitan Region, with a significant expansion over time. Woodlouse species, although common in the city, are sparsely sampled and so their EOO and AOO are underestimated. Stevenia deceptoria had a medium to complete overlap in distribution with potential woodlice hosts. The rapid expansion of S. deceptoria is probably due to its native host invading the Metropolitan Region. It is therefore likely that this fly species will expand its current distribution to neighboring regions where exotic woodlouse species are present.

      • Slide Session : OS-GAS-20 ; Gastroenterology : Haps (Harmless Acute Pancreatitis Score) Predicting a Non Severe Evolution in Patients with Acute Pancrea-titis in North Mexico

        ( Alejandro Garza Alpirez ),( Ana Fernanda Alvarado Villalobos ),( Luis Gonzalo Gomez Sanchez ),( Luis Alonso Morales Garza ),( Maria Teresa Sanchez Avila ),( Salvador Bruno Valdovinos Chavez ),( Mons 대한내과학회 2014 대한내과학회 추계학술발표논문집 Vol.2014 No.1

        Background: Prompt treatment of pancreatitis aims to identify using established scales, which patients will develop a complicated course and therefore, would benefit from a more aggressive treatment and closer monitoring. Objective: To assess the reproducibility of the HAPS score (normal creatinine and hemoglobin without presence of peritoneal irritation) in patients with acute pancreatitis and then compare the results of Ranson, APACHE II, CTSI and BISAP scales to determine their ability to predict non severe evolution. Methods: 62 patients with acute pancreatitis were evaluated. The most common etiology was biliary, with 36 cases (22 females [F] and 14 men [M]), followed by alcoholic with 12 cases (0F:12M), lipidic 10 cases (2F:8M) and idiopathic cases with 4 (4F:0M) and biochemical measurements were made to calculate the prognostic scales Ranson, APACHE II and BISAP (at income, 24 and 48 hours). An abdominal CT scan was also made in order to complete the CTSI scale. Results: HAPS correlated with Ranson and APACHE II, the two most used scales to assess patients with acute pancreatitis. 14 (22.5%) patients met the 3 parameters of HAPS score for the prediction of a non-severe evolution, of which only 1 had severe evolution. For necrosis, scales with better sensitivity and specificity were BISAP HAPS, CTSI and Ranson. While to organic failure the scale with better sensitivity was BISAP and with better specificity were HAPS and Ranson. Conclusions: The HAPS scale is a suitable tool for initial assessment of Mexican patients with acute pancreatitis of any etiology because of its ability to predict a non-severe evolution.

      • Genomic DNA분석을 위한 백혈구 추출 칩 개발

        지원호,김태곤,황승용,박진구 한양대학교 이학기술연구소 2004 이학기술연구지 Vol.7 No.

        혈액에서의 genomic DNA의 활용은 성별의 구별에서부터 질병의 유무 및 진단에 이르기까지 다양하게 사용되어지고 있다. 이에 따라 좀 더 효율적이고 빠른 genomic DNA의 분석이 절실히 요구되고 있다. 지금까지 혈액에서의 genomic DNA PCR을 위해서는 복잡한 genomic DNA 추출 과정이 선행 되었다. 본 연구에서는. 혈구세포내에서 유일하게 핵을 가지며 DNA를 가지고 있는 백혈구만을 선별 하여 이를 PCR 증폭을 수행하여 기존의 방법의 약 3배 정도 적은 시간과 화학물질을 사용하여 비슷한 결과를 얻을 수 있는 microfluidic chip을 설계하였다. Genomic DNA PCR (polymerase chain reaction) method must need to extraction step. We collected to the leukocyte that is only to have a nuclear and DNA in whole blood component. The exofcted leukocyte was applied to the PCR method in directly. A high effciency microfluidic chip was designed to extract leukocyte from whole blood using the lab-on a chip technology. This chip was able to the fast time and low chemical volume by 3-fold.

        Performance of mid-upper arm circumference to diagnose acute malnutrition in a cross-sectional community-based sample of children aged 6-24 months in Niger

        Sarah K Marshall,Joel Monárrez-Espino,Anneli Eriksson 한국영양학회 2019 Nutrition Research and Practice Vol.13 No.3

        BACKGROUND/OBJECTIVES: Accurate, early identification of acutely malnourished children has the potential to reduce related child morbidity and mortality. The current World Health Organisation (WHO) guidelines classify non-oedematous acute malnutrition among children under five using Mid-Upper Arm Circumference (MUAC) or Weight-for-Height Z-score (WHZ). However, there is ongoing debate regarding the use of current MUAC cut-offs. This study investigates the diagnostic performance of MUAC to identify children aged 6-24 months with global (GAM) or severe acute malnutrition (SAM). SUBJECTS/METHODS: Cross-sectional, secondary data from a community sample of children aged 6-24 months in Niger were used for this study. Children with complete weight, height and MUAC data and without clinical oedema were included. Using WHO guidelines for GAM (WHZ < -2, MUAC < 12.5 cm) and SAM (WHZ < -3, MUAC < 11.5 cm), the sensitivity (Se), specificity (Sp), predictive values, Youden Index and Receiver Operating Characteristic (ROC) curves were calculated for MUAC when compared with the WHZ reference criterion. RESULTS: Of 1161 children, 23.3% were diagnosed with GAM using WHZ, and 4.4% with SAM. Using current WHO cut-offs, the Se of MUAC to identify GAM was greater than for SAM (79 vs. 57%), yet the Sp was lower (84 vs. 97%). From inspection of the ROC curve and Youden Index, Se and Sp were maximised for MUAC < 12.5 cm to identify GAM (Se 79%, Sp 84%), and MUAC < 12.0 cm to identify SAM (Se 88%, Sp 81%). CONCLUSIONS: The current MUAC cut-off to identify GAM should continue to be used, but when screening for SAM, a higher cut-off could improve case identification. Community screening for SAM could use MUAC < 12.0 cm followed by appropriate treatment based on either MUAC < 11.5 cm or WHZ < -3, as in current practice. While the practicalities of implementation must be considered, the higher SAM MUAC cut-off would maximise early case-finding of high-risk acutely malnourished children.

      • 中, 長距離 選手의 競技力 向上을 위한 效果的인 指導 方法의 硏究 : Weight Training과 Circuit Traning을 中心으로

        박무철,오만석 安東大學 1991 安東大學 論文集 Vol.13 No.1

        I had exercised 16 middle and long-distance runners attending this school in Weight Training and Circuit Training to improve their running skills for 12 months. Having arranged and analyzed the improvement of their physical strength and their records, I had applied a training schedule and a record list system to them. So I came to the conslusion as follows. A. By means of exercising them in accordance with their aptitude, 1. almost all runners improved their physical strength, muscular staying power, softness, promptitude, etc. 2. they imporved their records remarkably by improving their physical strength and by an ideal running method. 3. they improved their physiques normally by a rational training method. B. By means of using a progressive coaching technique method and the record list in accordance with training schedule, 1. I could easily sieze the individual capacity and the fact that the runners went on doing their best. 2. the runners realized the importance of physical strength and exerted themselves to improve their records. 3. the runners trained with a firm faith without languor. C. The runners` respons after Weight Training and Circuit Training 1. Though they agonized physically and spiritually, more then 90% of them wanted to continue training. 2. More then 90% of them improved their records after the training and three sets which between a third and two-thirds of their capacity was used in were moderate tranining.

        Selective Migration and Economic Growth in México

        Jaime Lara Lara,Bernardo Garza Gómez,Dania Monárrez Barrón,Emilio Mátar Zambrano,Gustavo Vázquez García 중앙대학교 경제연구소 2023 Journal of Economic Development Vol.48 No.1

        The objective of this study is to determine the impact of selective internal migration on regional economic growth in Mexico. The net skilled migration rate has no significant impact on growth. The net migration rate is positively correlated with economic growth, but has no effect when endogeneity is solved. Together, the results indicate that there is no significant and robust causal impact of migration on growth. These results sustain even when we consider the negative effect that population growth rate have on regional economies.
